Synthesis of the polyvinyl alcohol (PVA)–starch (ST)–yttrium oxide (Y2O3) nanocomposites and studying their structural and dielectric properties are considered for the sake of high-sensitive pressure sensors. The nanocomposites are prepared by casting method. The PVA–ST blend is prepared with following concentrations: 85 wt.% polyvinyl alcohol, 15 wt.% starch. The effect of yttrium-oxide nanoparticles’ concentration on the structural and dielectric properties of PVA–ST blend is studied. The dielectric properties of PVA–ST–Y2O3 nanocomposites are examined in frequency range from 100 Hz to 5 MHz. The results show that dielectric constant and dielectric loss of nanocomposites are decreased with increase in frequency of applied electric field. The A.C. electrical conductivity increases with increase in frequency. The dielectric parameters (dielectric constant, dielectric loss, and A.C. electrical conductivity) of PVA–ST blend are increased with increase in yttrium-oxide nanoparticles’ concentration. The PVA–ST–Y2O3 nanocomposites are tested for pressure-sensor application. The results show that the electrical resistance of PVA–ST–Y2O3 nanocomposites decreases with increase in pressure.
Key words: conductivity, structure, Y2O3, nanocomposite, pressure sensor
